I had nothing fancy in mind. I wanted merely to build a Group and a
Ring following what has been done in CM with Field/FieldElement.
I already had the opportunity to mention this library, but Jean-Marie
Dautelle's JScience is a good example of implementation of all these
mathematical structures ( However, I tend to
prefer the way Fields are implemented in CM (there are slight
differences, most notably getZero() and getOne() which are missing in
If you are still interested, I'll post (not commit, I got the
